Cow Tools!
We have lived alongside cows for nearly 10,000 years.
We breed them and exploit them
It is now, only now, that we have discovered THEY CAN USE TOOLS
Here I describe our study

SPAR supermarkets are promoting a broom and stick set in Austria with Veronika.
It reads:
“Einstein among the cows: Spar sells Vroni's back scratcher set”
Vroni is the diminutive form of Veronika, of course.
Thanks to Özge Nasa for the tip!

Last week I had the privilege of speaking with @auersperga.bsky.social and @biotay.bsky.social about a very talented cow. She's called Veronika, she's fabulous and she's currently getting a lot of well-deserved attention. Here's my piece for @iflscience.com:

“We Didn't Even Think About Looking”: Broom-Wielding Veronika Shows Tool Use In Cows Isn't So Absurd After All
Veronika the cow is the first documented example of flexible, multipurpose tool use in cattle – and she’s also a very good girl.

1/4 The effect of psychedelics on animal models has been studied the WRONG way. .
Here they analyze 109 studies with psychedelics in rodents (from 2019 to 2024). In the vast majority of studies, the “set and setting” is the same as that which would be used in humans to cause a bad trip.

Normally, foals are separated from their mothers at 4 to 7 months of age. Under natural conditions, they remain with their mothers for up to a year. In this study, brain and metabolic development in both situations was compared.

This is one of the points we brought up in our recent paper about how risk management (esp. as it relates to toolmaking) may be different in early hominins than in living humans. Variation in social/cultural behavior is key! See here: link.springer.com/article/10.1...

1/7 Look, Mom, no hands!
They have studied the age at which chimpanzees take the most risks (jumping and doing crazy things from tree to tree). It turns out that they have a peak in childhood, and it decreases as they grow older. This tells us something very interesting about ourselves.
